4.2.6 Port 11
using port mode register 11 (PM11). When the P112, P113 pins are used as an input port, use of an on-chip pull-up
resistor can be specified in 1-bit units by pull-up resistor option register 11 (PU11).
Port 11 is a 2-bit I/O port with an output latch. Port 11 can be set to the input mode or output mode in 1-bit units
This port can also be used for segment output and serial interface data I/O.
Reset signal generation sets port 11 to input mode.
Figures 4-9 and 4-10 show a block diagram of port 11.
